Abstract

Dual rod-coil brush copolymer [Polynorbornene-graft-Poly(3-hexylthiophene)]-block-[polynorbornene-graft-Poly(ethylene oxide)] [(PNB-g-P3HT)-b-(PNB-g-PEO)] (P3HT-PEO) was synthesized via Grignard Method, click chemistry and Ring Opening Metathesis Polymerization to observe nanostructures. However, due to the unknown reason, early degradation was occurred disabling formation of architectures in the melts. Unique hollow nanoband was observed in DCM and Methanol solution, which may result from a coeffect of π-conjugated aggregation and microphase separation. And a clear transition between J- and H- aggregation occurs when changing solution mixtures in dual brush copolymer system.
